The New York Times recently published an article talking about how the Big Bang might sound if we could hear it.
From the article:
"Sound waves propagate with just the slightest disturbances. The sound of a voice compresses air by one part in five million. The differences in pressure in the primordial gases were 1 part in 10,000, and that corresponds to a satisfyingly loud, but not lethal, 110 decibels - rock concert volume."
"For the first 400,000 years," Dr. Whittle said, "it sounds like a descending scream falling into a dull roar."
Over the first million years, Dr. Whittle said, the music of the cosmos also shifted from a pleasant major chord to a more somber minor one."

Ahhh...we've migrated from "major to minor." It figures...
